this is a buy it, use it, park it tool.
you guys connect the dots,,
I bought my O2 meter and sensor about 25 years ago.....and I have used it 3 times. I used it the first time when setting up Webers on a sports car, then just last year I used it on a Savage, the again this year when I changed to the Mikuni VM36. Once you have the carb jetted properly you don't need it again.....till you make some other major change. I probably have abot $ 25 invested for each time I used it.....and the ability to know what is going on was worth the price of admission to me. I would have eventually gotten the right jets by trial and error....eventually!
